Question

The sum of 5 consecutive no is 200 . What is the average of last three no

Answer 1

Step-by-step explanation:

let the five terms are

X,X+1,X+2,X+3,X+4

by given condition

X+X+1+X+2+X+3+X+4=200

5X+10=200

5X=200-10

5X=190

X=38

average of last three terms=X+2+X+3+X+4/3

=38+2+38+3+38+4/3

=123/3

=41
